Solve for C (complex solution)
C=-i\ln(\frac{i\sqrt{8c^{2}-81}+2\sqrt{2}ic}{9})+2\pi n_{1}\text{, }n_{1}\in \mathrm{Z}
C=-i\ln(\frac{2\sqrt{2}ic-i\sqrt{8c^{2}-81}}{9})+2\pi n_{2}\text{, }n_{2}\in \mathrm{Z}\text{, }c\neq 0
Solve for C
C=arcSin(\frac{2}{9}c\times 2^{\frac{1}{2}})+2\pi n_{12}\text{, }n_{12}\in \mathrm{Z}
C=\pi +2\pi n_{21}+\left(-1\right)arcSin(\frac{2}{9}c\times 2^{\frac{1}{2}})\text{, }n_{21}\in \mathrm{Z}
Solve for c
c=\frac{9\sqrt{2}\sin(C)}{4}
\nexists n_{1}\in \mathrm{Z}\text{ : }C=\pi n_{1}
